The FFMpeg command line moved in the 7.0.1 Patch. To apply the Video Quality Mod make the following change;
Location: /flash/modules/video/inc
File: header_inc.php
CHANGE: LINE 17 "play" => $GLOBALS['sFfmpegPath'] . " -y -i #input# -r #fps# -s #size# #video_filters# #audio_options# #output#",
TO: LINE 17 "play" => $GLOBALS['sFfmpegPath'] . " -y -i #input# -r #fps# -s #size# -qmin 3 -qmax 6 #video_filters# #audio_options# #output#",
